Has anyone made it past the "batch" of lenses with issues? I've had 4 copies with clicking noises, a lens with a bubble in the front element, two lenses with AFMA issues at 70 mm (both were amazing at 24 mm, but awful at 70 mm) and a lens that was great until wider than f/4, then the resolution plummeted. So, this is eight copies that I've tested with origination dates from Oct 2012 through June 2013.
I know that there are good copies of this lens out there. Actually, I almost kept the copy with a small bubble as it was great in every other way. As was the one copy with the clicking issue that I tested (other three I sent back as soon as I heard the clicking).
But I just want to see if anyone has recently purchased a good copy of this lens?
BTW, I've tested my other lenses and the 24-70 II is the first lens I've ever returned.
Also, for those of you that have to hold your ear up to the lens to hear the clicking....that is much softer than what I've experienced. The four that I had with the clicking it was audible enough that I instantly heard it with the lens at a normal distance (18 to 24 inches) from my ear.
